Based on the search results, it is not clear what national holiday it is today. However, there are several websites that keep track of fun holidays and special moments on the cultural calendar, giving exciting activities, deals, local events, brand promotions, and other resources. Some of these websites provide information on national days, but they do not indicate which national day it is today. Therefore, it is recommended to check official government websites or local news outlets to find out if there are any national holidays or observances today.
